How To Weld Bronze Together. Welding uses high-heat fusion to bond each of the metals together. You can also get bronze.
The steel tube and plate are heated to bright red heat and the brazing rod filler. It takes a lot of continuous heat to achieve welding with this metal. Working with copper brass or steel requires soldering the alloy with a phosphorus flux.
With TIG you need DC current and pure argon shielding gas.
The best option for welding steel to copper is actually a brazing technique since the melting points of steel and silicon bronze the required filler metal are so disparate. You can use silicon bronze filler wire and a TIG welder to weld steel to copper most easily while maintaining as strong of a bond as possible between the two metals. Oxy acetylene welding uses high pressure gas cylinders that contain the two gases oxygen and acetylene. The steel tube and plate are heated to bright red heat and the brazing rod filler.
